Laser cutting air compressor

All Laser Cutters need two additional gadgets which move air: blower which removes air flow / extracts smoke from machine and atmosphere compressor as a source for compressed surroundings for so called air assist.

Why and How
Laser cuts by warmth, very high temperature focused in tight beam. Side items of high heat are smoke and fire, both aren’t welcomed addition, smoke disperses laser beam reducint it’s efficienty and fire causes charring of material / edges and can even get out of control leading to serious emergency.

Fire needs air to burn nonetheless it can also die in the event that you blow too hard, think of a candle in the wind. This is essentialy what air flow assist is normally for: compressed air flow is extruded directly at the laser head in a very limited stream and is fond of where laser touches material. pressure and level of air
Pressure of air is essential variable for air help efficienty, in our shop we found out that optimal worth is between 2 and 3.5 bar (31-50psi).

To attain required pressure compressor must push certain volume of air through air flow assist opening, exact volume depends upon size of the starting and desired pressure. Top quality laser beam cutter heads have little and finely tuned openings while cheaper chinese cutters simply blow in general direction via huge holes.

Proper compressor
When choosing compressor you have to consider if it will be able to constantly provide desired pressure and level of air. Little airbrush compressors small compressors boast amazing pressure figures but really poor flow rates sufficient only for airbrush pistols. Even if small compressor can push enough air it’ll likely overheat in couple of minutes.
